Abrasion Rasistant Steel Plate

We can supply abrasion resistant steel in the form of gas or plasma cut profiles to exacting tolerances or as formed, drilled, or machines parts. It is of course also available as plate straight from our stocks.

Utilised in applications such as tipper bodies, cutting edges, crushing machinery, and excavator buckets abrasion resistant plate from Champak Steel & Engg. Co. is sourced from Indian producers and is available in 400, 450, and 500 Brinell hardness, in thicknesses from 3 mm to 60 mm, and up to 12 metres by 2 to 2.5 metres in plate size.

Abrasion Resistant Steel Plate Excellent Abrasion Resistant 4 or 5 times stronger than ordinary steel Excellent Workability Larger in elongation and better in workability Excellent Weldability Decrease deformation rate Wide range of sizes Available in a wide range of sizes

Fabrication of Abrasion Resistant Steel :

Welding

Abrazo 400 can be welded under normal conditions (if you require advice on welding, machining or forming then please contact any one of our offices) using MMA, MOG and SAW without preheat, up to a combined thickness of 60mm, provided hydrogen controlled electrodes are used. Consumables should be dried in accordance with scale D of BS 5135. Consumables should be chosen on the basis of whether or not the weld metal is exposed to wear conditions.

Machining

Machining or drilling is more difficult due to hardness. For 400BHN use high-grade cobalt HSS E drilling tools and for 500BHN hard metal drilling tools are necessary.

Forming

Abrasion steels can be readily cold formed. Compared with steels of lower yields, three factors should be considered:
1.  Higher press forces.
2.  A greater bend radius is required.
3.  Spring back.

Flame Cutting

Material can be cut using conventional flame cutting practices without the need for preheat at ambient temperature.The following cutting parameters are recommended.

Milling

Abrasion resistant steel can be machined by milling. The following recommendations are given for general guidance.

* For further information on 450, 500 please contact us for details.

Cold Bending

Where possible, cold bending should be carried out with the bend axis perpendicular to the rolling direction, this being the less onerous of the two directions. The following table contains guidelines for bending to a 90░angle. In general however, bending radii should be as generous as possible.
